    I didn't know where to post this, so if it's posted in the wrong section, an admin / mod can move it ;)

    This is the pinlayout of the front-panel audio header on my motherboard:

    GND
    GND
    +5VA
    BACKOUT-R
    BACKOUT-L
    AUD-OUT-L
    AUD-OUT-R
    MIC-POWER
    MIC


    AUD-OUT-L & AUD-OUT-R is the stereo output
    BACKOUT-R & BACKOUT-L is the return signal if no plug is inserted in the jack of the front panel, in this case the signal is sent to the standard output on the backpanel of the motherboard (this info was obtained with google, so don't shoot me if it's wrong :p)

    I'm planning on making a headphone out from this header, in my backpanel there will be a 5.1 set connected

    I'll be connectiong the JR1 and JL2 jumpers on my motherboard 2 jumpers (Note: If JR1 and JL1 Jumpers are short, both the front panel and the rear panel audio connectors can work.).

    My question is, what do I have to do with the BACKOUT-R & BACKOUT-L from the front panel header, I only found the function on google, not HOW it works :s

    You miss the point. For fron and rear to work all have to be connected like this

    MB > AUD-OUT-L > front pannel > BACKOUT-L > back pannel.
    This is how the audio works
    When the headphone connector is put in front pannel the audio comes from AUD-OUT-L into headphones, when the connector is removed the circuit is reconnected and the signal is sent to the rear pannel via BACKOUT-L.
    the jumpers are there to bypass the front pannel leads, you cant have the jumpers and the leads connected at the same time.

    To be extremly rude RTFM its printed clearly in the manual under eather jumpers or front pannel sections.

    to be normaly rude to you : STFU

    read my post, and the extract from the manual (so I did read the manual ^^ :sigh: )
    I'll even quote so that an idiot like you can't miss it :


    and yes, it can be that I clearly miss the point, but as indicated in my first post, I haven't found any info about "the point" ^^

    I found this here :

    And on my motherboard, the jr1 and jl1 jumpers are shorted (stock) So I guess I won't need to connect the return signal if I leave these connected
